Lighting — FAQ
What color temperature is best for night lights?
3000K soft white works best for bedrooms and hallways, providing warm illumination without disrupting circadian rhythms. 5000K daylight suits bathrooms where color accuracy matters for safety. Avoid cool blue tones above 6000K at night.
How bright should a night light be?
10-30 lumens suffices for most spaces—enough to navigate safely without disturbing sleep. Use 50-100 lumens for stairs or high-traffic areas. Start dim and increase only if needed; excessive brightness defeats the purpose.
Do dusk-to-dawn sensors really save energy?
Quality sensors cut energy use by 90% versus always-on lights. They activate only in true darkness, eliminating daytime waste. Tested models consume 0.5W when lit, costing pennies annually. Avoid cheap sensors that trigger prematurely.
Are plug-in night lights safer than battery models?
UL-listed plug-ins are safest for permanent use—no battery leakage or recharging hassle. Battery lights suit temporary placement but require maintenance. Rechargeable lithium units balance portability with safety when certified.
Can night lights interfere with sleep quality?
Blue-rich light above 4000K suppresses melatonin. Choose 3000K or lower with dimming capability. Position lights low to the ground and away from the bed. Red or amber night lights cause minimal sleep disruption.
How long do LED night lights typically last?
Quality LED night lights last 50,000+ hours—over 11 years of continuous use. Sensor components may fail sooner. Look for 2-3 year warranties covering full replacement. Avoid units with visible LED filaments; sealed units last longer.
